It sounds like a reverse look-up issue! sendmail will try to do a gethostbyaddr() which can take 25 seconds / try.... The insane thing is that after a failure, it will log it, and then go ahead and perform it's function. IIRC there is a way to defeat the lookup, but I try to fix things! Check the ip addresses that have the long delay for proper reverse functionality.... dig -x ip.ad.re.ss If their reverse doesn't work, you or the client must tell their ISP to fix it!
